SWEDE BEAM SYSTEM: A SCANDINAVIAN FLOOR STRUCTURE

The system, consisting of precast and pretensioned concrete beams in combination with cast in situ concrete slabs has been modified to add compressive stresses to the slabs to avoid cracks in the concrete surface. The slab is cast using large tableforms supported by steel trusses resting on the lower flange of the beam after the precast beams have been erected and jacked up by shoring to the predetermined height. A minimal amount of welded mesh reinforcement is required in the slab since it remains completely prestressed. The liquid concrete is vibrated with a poker and vibrating screed and is immediately covered with a pliable mat. Vacuum dewatering is carried on at a rate of about one minute per cm of thickness. It is claimed that time savings introduced by the use of the method can reduce floor structure costs by about 30 per cent. Maintenance costs are also greatly reduced by the construction of the impermeable concrete floor. (Author/TRRL)
